To determine whether the Veterans Health Administration's (VHA) efforts to expand access to home- and community-based services (HCBS) after the 2001 Millennium Act significantly changed Veterans' utilization of institutional, paid home, and unpaid home care relative to a non-VHA user Medicare population that was not exposed to HCBS expansion efforts.
We used linkages between the Health and Retirement Study and VHA administrative data from 1998 until 2012.
We conducted a retrospective-matched cohort study using coarsened exact matching to ensure balance on observable characteristics for VHA users (n = 943) and nonusers (n = 6106). We used a difference-in-differences approach with a person fixed-effects estimator.
DATA COLLECTION/EXTRACTION METHODS: Individuals were eligible for inclusion in the analysis if they were age 65 or older and indicated that they were covered by Medicare insurance in 1998. Individuals were excluded if they were covered by Medicaid insurance at baseline. Individuals were considered exposed to VHA HCBS expansion efforts if they were enrolled in the VHA and used VHA services.
Theory predicts that an increase in the public allocation of HCBS will decrease the utilization of its substitutes (e.g., institutional care and unpaid caregiving). We found that after the Millennium Act was passed, there were no observed differences between VHA users and nonusers in the probability of using institutional long-term care (0.7% points, 95% CI: -0.009, 0.022) or in receiving paid help with activities of daily living (0.06% points, 95% CI: -0.011, 0.0125). VHA users received more hours of unpaid care post-Millennium Act (1.48, 95% CI: -0.232, 3.187), though this effect was not significant once we introduced controls for mental health.
Our findings indicate that mandating access to HCBS services does not necessarily imply that access to these services will follow suit.
确定退伍军人健康管理局(VHA)在 2001 年千禧年法案之后扩大家庭和社区服务(HCBS)的努力是否会显著改变退伍军人对机构、付费家庭和无偿家庭护理的利用,与没有接触 HCBS 扩张努力的非 VHA 用户医疗保险人群相比。
我们使用了健康与退休研究和 VHA 行政数据之间的联系,时间范围从 1998 年到 2012 年。
我们进行了回顾性匹配队列研究,使用粗化精确匹配确保 VHA 用户(n=943)和非用户(n=6106)在可观察特征上的平衡。我们使用差分法和个体固定效应估计量。
资料收集/提取方法:如果个体年龄在 65 岁或以上,并在 1998 年表示他们受医疗保险保险覆盖,则有资格参与分析。如果个体在基线时受医疗补助保险覆盖,则将其排除在外。如果个体参加了 VHA 并使用了 VHA 服务,则认为他们接触了 VHA 的 HCBS 扩张努力。
理论预测,HCBS 的公共分配增加将减少其替代品(例如机构护理和无偿护理)的利用。我们发现,在千禧年法案通过后,VHA 用户和非用户在使用机构长期护理的概率方面没有观察到差异(0.7%,95%CI:-0.009,0.022)或在接受日常生活活动的有偿帮助方面(0.06%,95%CI:-0.011,0.0125)。VHA 用户在千禧年法案之后获得了更多的无偿护理时间(1.48,95%CI:-0.232,3.187),尽管在引入心理健康控制后,这一效果并不显著。
我们的发现表明,强制获得 HCBS 服务并不一定意味着这些服务的获得就会随之而来。
